Fracture and Post-Cracking Behavior Prediction for Glass and Carbon Fibre Reinforced Concrete Construction Members

Experimental investigation of AR glass fiber and carbon fiber concrete strength and post cracking non-linear behaviour were realized. Simultaneously fiber pull-out micromechanical investigation was realized experimentally (for glass and carbon single fiber and fiber bundles) and numerically (using FEC ANSYS). Structural fiberconcrete fracture model were elaborated. On the base of micromechanical results predictions for fiberconcrete non-linear post-cracking behaviour were successfully made for fiberconcrete prisms subjected to 4-point bending. Model predictions were experimentally verified
